During the U.S. Food and Drug Administration's advisory panel hearings to evaluate the premarket approval for conventional silicone gel implants on October 14 and 15, 2003, panel members and patient advocate representatives focused on four specific areas of concern: reoperation rates in primary breast augmentation; levels, depth, and methods of patient education and informed consent; modes, frequency, and management of silicone gel implant device failures, including management of "silent" ruptures; and methods of monitoring and managing symptoms or symptom complexes that may or may not be associated with connective tissue disease or other undefined symptom complexes. These concerns, with a reported 20 percent reoperation rate for primary augmentation within just 3 years, and a lack of concise, definitive management protocols addressing these areas of concern may have contributed to the Food and Drug Administration's rejection of the premarket approval, despite the panel's recommendation for approval. This article presents decision and management algorithms that have been used successfully for 7 years in a busy breast augmentation practice (Tebbetts and Tebbetts). The algorithms have been further expanded and refined by a group of surgeons with diverse experiences and expertise to address the following clinical situations that coincide with concerns expressed by patients and the Food and Drug Administration: implant size exchange, grade III to IV capsular contracture, infection, stretch deformities (implant bottoming or displacement), silent rupture of gel implants, and undefined symptom complexes (connective tissue disease or other). In one practice (Tebbetts and Tebbetts) that uses the TEPID system (tissue characteristics of the envelope, parenchyma, and implant and the dimensions and fill distribution dynamics of the implant), implant selection is based on quantified patient tissue characteristics, pocket selection is based on quantified soft-tissue coverage, and anatomic saline implants have fill volumes that are designed to minimize shell collapse and fold fatigue; in this practice, the algorithms contributed to a 3 percent overall reoperation rate in 1662 reported cases with up to 7 years of follow-up, compared with a 20 percent reoperation rate at 3 years in the 2003 premarket approval study.
在2003年10月14日和15日美国食品药品监督管理局咨询小组听证会上,评估传统硅胶乳房植入物上市前批准申请时,小组成员和患者权益代表重点关注了四个特定的问题领域:初次隆乳手术的再次手术率;患者教育及知情同意的程度、深度和方式;硅胶乳房植入器械故障的模式、频率及处理,包括“隐性”破裂的处理;以及监测和管理可能与结缔组织病或其他不明症状复合体相关或无关的症状或症状复合体的方法。这些问题,加上据报道仅3年内初次隆乳再次手术率就达20%,且缺乏针对这些问题领域的简洁、明确的管理方案,可能导致了食品药品监督管理局拒绝该上市前批准申请,尽管小组建议批准。本文介绍了在繁忙的隆乳手术实践中已成功使用7年的决策和管理算法(特贝茨和特贝茨)。一组具有不同经验和专业知识的外科医生对这些算法进行了进一步扩展和完善,以应对与患者及食品药品监督管理局所表达的担忧相符的以下临床情况:植入物尺寸更换、III至IV级包膜挛缩、感染、拉伸畸形(植入物下沉或移位)、凝胶植入物的隐性破裂以及不明症状复合体(结缔组织病或其他)。在一种使用TEPID系统(包膜、实质和植入物的组织特征以及植入物的尺寸和填充分布动态)的实践(特贝茨和特贝茨)中,植入物选择基于量化的患者组织特征,腔隙选择基于量化的软组织覆盖情况,解剖型生理盐水植入物的填充量旨在使外壳塌陷和折叠疲劳最小化;在这种实践中,在1662例报告病例中,经过长达7年的随访,这些算法使总体再次手术率为3%,而在2003年上市前批准研究中3年时的再次手术率为20%。
